i need help!! please!!!!

So on sunday night, car started over heating :( i thought it was the water pump but i came to realize that my radiator fans stopped working. Its throwing code p0691 and its says there a short to ground for fan 1 but i have checked all connections with no luck. Ive been at it since monday morning and i cant figure it out. I replaced the fan control module and that set me back 450 bones as it is. Please, if you guys have any idea, comment up. I have checked fuses aswell but if you guys no if there is a fan relay let me know. Thank yoi

Maybe you should check the resistance across the fan motor. Maybe it's shorted internally?

I cannot find a P0691 in ElsaWin. Giving zero info on your car is not helping anyone either. You replaced the fan control module, but did you verify either or both fans are working with a 12v power source?

So heres alittle more info. The car is 2009 audi b8 a4. Both fans were checked and they both spin freely with a 12v battery source. How do i go about checking resistance of fans? I think if they were bad they wouldnt spin with the 12v source

What module did you pull that code from? I couldn't find it in the ECU list.

I got it from the wngine module off vagcom

Also, when i clear that fault, its fine. But as soon as i start the air conditioner at lo temps, it comes right back up.

So... This morning i turned on my car and the fans came on when i put the temperature all the way down to low. Now i turned off the ac and that stopped the fans but when i turned it back on, they didnt come back on

There is a relay (J317) in the circuit. But if it were bad (by bad I mean relay is not energized and allowing power to go to fuse SB11), power would not be applied to fuse SB11 which is located under the hood. From the looks of it, that power wire eventually goes to the coolant fan control module (terminal 2, it is a red/green wire). So maybe check that fuse SB11 under the hood and see if it is receiving power when it should (problem is I don't know when exactly it is supposed to receive power from the relay, when AC is on perhaps?). There is another wire supplying power at terminal 1 of the fan control module, it is the thicker red wire if the diagram is accurate.

Not sure if you can do this with VCDS but its worth a shot, see if you can enter into special functions and perform an output test and see if it activates the relays and all that good stuff. Probably a better way to check out the wires compared to when to engine is running and things are hot and moving around.

Is there a diagram for the fuses under the hood? I couldnt find a diagram at all for them unfortunately. Also, where can i find relay j317? I really appreciate the help fellas.
